ABSTRACT:
Apparatus and method for optical inspection of fruit without rotating or otherwise repositioning the article during inspection. Plural mirrors are positioned to view different surface portions of each article moving along a path, and those mirrors consolidated the partial images to form a composite image viewable at a common objective such as a video camera. The images from individual mirrors are directed toward a pyramid having reflective surfaces, aiming those partial images toward the common objective aligned with the vertex of the pyramid. A holder supports each article above a conveyor with minimal surface contact, thereby minimizing portions of the article not visible for optical inspection.
